ANTIRATTLE wmnow LOCK.

Y Appneation filed rebruary 23, 1923. seriai No.'e2o,ee1.

This invention is an improvement inV thatV class of anti-rattle andburglar proof locks for window sashes in whicha friction device isslidably mounted on a base and is operable by a lever pivoted to .thebase, to engage one window sash of a pair of sashes, to the other sashof which pair the base is fixed. f Y v Said locks are applicable to awindow sash singly tov prevent rattle, or in pairs to insure againstentrance of burglars, and an object is to adapt the improvement to bothright and left members of a pair of theY locks so that the release willoperate satisfactorily in either and both of such locks when properlyinstalledV on a sash. l

An object is to provide a simple and effective construction whereby thelock can be easily released. f

A feature of myrinvention is to provide a screw forA the actuating leverwhich screw serves to secure the lock to the sash.

Other objects, advantages and features of invention may appear from theaccompanying drawing, the subjoined detail description'and the appendedclaim.

'The accompanying drawing illustrates the invention. j v

Figure 1 is a broken perspective view showing a pair of window locksequipped with my vimprovement and installed on a window; a fragmentA ofwhichV is shown. The lock at theleft is shown as having been moved tounlocked position while that at the right is in locking position insolid lines and unlocking positi'onlin dot and dashlines. Fig. 2 is aplan of the window lock shown in the left of Fig. 1. A fragment of theupper sash and the frame are shownin section. Dot and dash linesvindicate the parts in locking position. f Fig. 3 is a section on linew3, Fig.2. Fig. 4 is a section on line @s4-m, Fig.' 2, showing thedevice in locking position.

Fig. 5 is a section on line x4-m5, Fig.A 2, showing the device inunlocked position.l

Fig. 6 is an elevation taken from the left of Figs. 2 and 3. A The locklto whichthis improvement is applied comprises three parts, as base 1, alocking slide 2 and locking lever 3 connected to each other and to thetop of the lower sash a ofia window by the screw 4 whichacts as a pivotfor the lever 3. 'The base 1 is attached to said lower sash by screws 5.TheV slide 2 is provided with a slot 6 through which the screw 4 isinserted ,p f and flanges 7 upturned from thefbase 1 L form a guidewayfor the slide 2. ,Said slide v2 is provided with frictional sashengaging means8 consisting of a block 9 preferably of rubber mounted ina holder 10 that'is formed by an upturned end,V of the slidey ipressedinto shape. The engaging means 8 ispmoved intol sash engagingposition by means of the lever 3 which is rounded at one end 11`toengage the meansS, and is prof vided at the other end with a handle or nthumb piece 12, and is adaptedto turn on the screw 4. Y

In the present invention l have provided',

the slide 2 with -a shoulder, yknob or protuberance 14 struck up fromthe slide and so positioned that when the lever is moved from lockingposition itY will act upon the knob to retract the slide 2 with itsmeans8 from sash engaging position.

The manner of applying thev employed heretofore and the operation islocks to the window is substantially theV same as that n.

the same excepting that when a'handle 12 is turned toward the center `ofthe .window5 f the same being toward the right of-thelefthand lock andtoward the left of the righthand lock, the lever contacts with theshoulder boss or knob 14 and operates arslide.

Said boss or Vknob `is struck up from the slide close to one vedgethereof and at` such v a distance .from block 10 to allow the roundedend vofthe lever to Vfit betweenthe block and the projection 14, so thatthe action ofthe lever willl be such as to easily actuate'the slide toperform its. function.

I claim: Y 'In an anti-rattle window lock, comprisin a base, screwsadapted to extend throng said base into the upper edgeof the lower sashof a Window, integrally formed up* wardly extending flangeson the sidesof said base, a slotted slide adapted to move longitudinally betweensaid flanges, a lholder in-l tegral with saidslide and 'arranged at oneend thereof, a rubber block carried by said 1 holder, a lever, a screwextending through the lever and base andadapted to be screwed by saidlever to ymove the slide out of sash into a sash through` the Slotl in'said slide to, engaging position. pivot said lever, said lever beingadapted to i engage said holder to move lsaid slide into my hand at LosAngeles, California, this sash lengaging position andv ya projection'Y17th day of February, 1923. struck up on said slide near one edgevtherefv of',"adapted and arranged to be acted upon l LUTHER HILL.
